The script will take files or dirs as parameters and will back them up in a

As you build up BK_LIST, you lose the ability to tell which spaces are
the ones you added, or were already in $PARAM. You end up treating all
spaces as word separators.
To fix this, you want to make BK_LIST an array:
BK_LIST=()
# or declare -a BK_LIST, but I prefer the former
Append to the array with +=
BK_LIST+="${PARAM}"
Expand the array, preserving spaces:
tar -cjf $BK_FULLPATH "${BK_LIST[@]}"
